Professional cleaning the focal lens of laser cutting systems

WARNING:

Please be aware of your national laws and regulations for the usage of hazardous substances and the instructions in your manual!

• In order to guarantee consistent cutting quality, the meniscus lenses used in the optical head of the systems must be inspected daily and cleaned of any visible soiling.
• Cleaning and inspection of lenses must only be carried out by appropriately trained personnel and is undertaken at the user’s own risk.

 The following precautionary measures must be observed when cleaning the ZnSe lenses:

• Always observe the operating instructions for acetone, ZnSE and for the equipment used by the owner.
• Handle the ZnSe lens and optical components with extreme care. This applies especially to burnt or broken lenses. The particles released in this case can cause serious damage to health.
• Avoid the material coming to contact with the skin.
• Never touch the optics or lens with your bare fingers. Greasy or dirty hands soil the surface and shorten the service life of the lens.
• Always wear finger stalls or gloves made of synthetic material. Do not use cotton gloves, because these are not lint-free.
• Always store lenses that have not been used or that have been dismantled in the lens paper provided in the scope of delivery.
• A scratched or burnt lens must no longer be used!
